Summary: This particular one I got did not work at all. Any battery you put into this immediately drained (in about a minute) and the device would shut down. I wish I had sent it back in time before the window for a refund was exhausted.
Summary: An excellent trimmer for sure, especially for the money, but this one and the one previous quit in less than 6 months. Not like the one I bought 15 years ago (looks like the same thing, essentially). The old one still worked 12 yrs later. Save on shipping.
Summary: I've been using this clipper to shave my beard twice per week for the last 2 years. All I've done for maintenance is swap in a new AA rechargeable when it starts to slow down (every 3 weeks or so). Small in size, very convenient, great for travelling.
